Vented Loops for $9.95!

For those planning to do away with the sprinkler valves but keep the stock fill hose, below is a link to vented loops for $9.95 + shipping. Total cost for 3 including shipping is $36.75. Mandley and I ordered 3 each so there are only 4 left so you better hurry if you want to take advantage of this great deal.

That's definitely a good deal! I'm glad so many Moomba owners are taking advantage of our research to upgrade their systems so they function like they should have from the factory!

Forgive my ignorance; what does the vented loop do, and where does it go?

Check out our blog for an explanation of vented loops (http://media.wakemakers.com/2009/06/stop-unwanted-filling-and-draining-with-a-vented-loop/), and what they do for ballast systems.

Holy Cow - $27.99 for those puppies on sale for $10? NICE :mrgreen:
I'm ignorant on the issue as well. So if using these you would take out the sprinkler valve and run a straight hose from the pump to the "vented loop" and then to the bag??

Keep in mind I have a DD and only 1 plumbed bag at the moment and it has 1 fill pump, sprinkler valve, and then the bag with 2 outlets on the top of the bag. The Starboard side has a drain pump and the port side is just a hose to the fitting (not exactly sure why).

Like I said - stupid on the issue :)

Just to clarify, the items sold on ebay were not the same brand as the ones we carry. Not that ours are necessarily worth the extra money, but just to make it an apples to apples comparison.

In order to get rid of the sprinkler valves you must do two things:

- Install a vented loop (which prevents siphon filling and draining
- Remove the factory scupper intake from the hull of the boat (either by cutting it off or replacing the entire fitting)

It is these two changes together that are required on Supra and Moomba boats to prevent the bags from filling and draining, one or the other will not work.

Viking,

You got it right. To eliminate the restrictive sprinkler valve, you would mount the vented loop as high as possible and as close to the bag as possible then run hose from the pump to it then to the bag. As Jason says, you also need to either cut the cup off the scupper or replace it altogether with a mushroom type intake.

viking,

The cup or scoop on the scupper forces water into the intake thru the fill pump, and into the bags since we have removed the sprinkler valves. The vented loop prevents this from happening. It also prevents water from draining back down thru the fill lines when at rest.

The look just like the thru-hulls on the side of the boat for the ballast discharge.

So the Scupper style actually forces water in and this Mushroom style does not??

Does the two way pumps then empty through the same mushroom intake is that how that works??

Well guys, I got burnt on these. Once in a while, the old adage "you get what you pay for" applies and it does here. Below is a pic of the $9.95 vented loop vs one I bought at West Marine for $28. The one from West Marine is made out of glass reinforced Marelon so they are able to make the walls thinner resulting in a larger inside diamter. The ones I received, although stated as being made of Marelon in the listing, are made out of plastic and have a dramatically smaller ID resulting in poor flow. I've contacted the seller and requested a refund. We'll see what she says. I hope no one else besides mandley bought these because of me. If you did, I apologize. Suggest you contact the seller like I did and see if she values her feedback enough to make things right. Be sure to include a copy of this pic in your e-mail to her.

Seller apologized and prompty refunded my purchase price including shipping and said she didn't want the items back. All's well that ends well.

Maybe you can use them for some kind of yard game now :)
